IMPROVEMENT m MACHINES FOR PonNcme HATS.

Specification forming part of Letters Patent No. 173,402, dated February15,1876 application filed January 22, 1 75.

To all whom it may concern:

Be it known that I, FRANCIS R. GOING, of Boston, in the county ofSuffolk and State of Massachusetts, have invented Improved Machine forPouncing Hats, of which the following is a specification: I

My invention relates to a machine for pouncing hats; and consists inmechanism whereby the hat-block, as it is rotated, has imparted to it arapidly-vibrating motion in the arc of a circle. t

Figure 1 is a partial section of a pouncingmachine provided with I myimprovements. Fig. 2 is a top view thereof, with the block andblock-carrier broken away. v

Inthe drawing, A represents the frame of the machine, of any desiredshape, to support the working parts. D is the drivingshaft, providedwith the usual fast and loose pulleys d, and with belt-pulleys d and dPulley (Z is double,'and scored to receive a band, 1', that connectssuch pulley with the scored pulley e on shaft E, proyided at its otherend with a toothed wheel, 0 that engages another toothed wheel, 0 on ashaft, 6 provided with a worm-gear, 6", that engages teeth I) of atoothed rim, S, secured to hub b of rotating platform-B, sustained in atubular bearing, a, projecting from the top plate a, mounted on frame A.The band 1" maybe changed in the grooves of the pulleys d c, to changethe speed of shaft E, and consequently the speed of the platform B,which derives its progressive ro-v tary motion from theshaft E, by thegearing described. The ,huh 7) serves as a bearing for and to supportthe rotating spindle O,"rest-ing on a suitable footstep in the frame,and, preferably, provided with means for lubricating it or containingoil. This spindle O derives its motion from the belt f, connected withpulley d, on shaft D, the pulley al being larger than pulley c onspindle O, so as to drive the spindle rapidly. The spindle has, justabove the top of the rotating platform B, an eccentric, 0, and abovethat a projecting pin,c A vibratingconnecting-link, G, preferably madeas a ring, is pivoted at g to the top of the rotating platform, and armsh, preferably flexible, and made of leather, or steel, or indiarubber,connect the sides of the link or ring centrally with an eccentricstrapor collar,'@' 43,

that surrounds the eccentric c. The rotation of the spindle 0 causes theeccentric to vibrate,

the link G about its pivotal point 9, and this it does as the rotatingplatform B revolves slowly. The block-carrier J has a sleeve, j,

I that surrounds the end 0 of the rotating spindle O, and an ear, Iprojecting from the blockcarrier is connected with a pin on aprojection, 1 rising from link G. This block-carrier is a disk providedwith pins 1, preferably three, that enter holes in the bottom piece 0 ofthe shell-like hat-block Q. 'A brake N, pivoted to top plate a, andcontrolled by a screw, or, in a lug, a, bears on B, and keeps its motionsteady. I

The operation of the machine is as follows: A hat-body is fitted overthe hat-block or shell 0, held on the block-carrier by the pins 1. R0-tation of shaft D imparts a slow rotary movement to the rotatingplatform, and it, asit'rotates, carries with it the pin that connectsthe link G with the platform. As the platform moves, this pin g changesits position about the central spindle 0, yet the eccentric on thespindle, as the spindle rotates, vibrates the link,'and the link,through its connection at ll with the block-carrier, vibrates theblockcarrier and hat-block rapidly in the arc of acircle about thecentral pin 0 The hat-body in this way gets .a short, rapid, vibratingor gigging motion, and at the same time its position is constantlychanged, owing to the slow rotation of the platform B. The workman holdsthe pouncing material by hand, or by a suitable pouncing-tool,preferably such a one "as is described in an application made by me forpatent and the movement of the hat-body is such that the action of thepouncing mate rial is substantially the same as it would be if the hatwere pounced in thebest manner by hand, for then the operator holds thehatbody while he rubs the pouncing-snrface held in his hand back andforth on the body, and at the same time turns the hat-block and hatbodygradually around.

In all hat-pouncing machines. heretofore made, so far as I am aware, thehatblocks have been round, and such construction was necessary, as thespindles that carry the blocks were turned around, first in one and thenin the other direction, giving to the hat-block such an extent ofmovement that it has been considered impossible tomachine-pounce a.

hat with an oval crown, because the pouncing material held by theoperator would. bear with unequal force against the surface of thehat-body, continually changing its position with reference to its centerof motion.

With this my machine, giving the hat-body a short vibrating or giggingmotion, coupled with a slow rotation about its central spindle O, I amenabled to pounce a hat of any desired shape, round or oval, and eitherstifl or unstiffened, and a hat may be completely pounced or finished onthe machine, instead of being finally hand-pounced a little, as is theusual custom in connection with good work.

By the term rotary platform, I mean to include a rotating surface orarm,'capable of carrying the pin on which the link G is pivoted, and itwill be seen that the remaining portion of the platform B, shown in thedrawings, could be easilydispensed with.

- It will also be obvious that the construction of the parts might beotherwise changed without departing from my invention, and I may employany other configuration of the parts B G J, so long as they, inconnection with their rotary driving mechanism, impart to the hat-blockthe motions herein described.

The hat-block is preferably a shell of felt, paper, wire-gauze, or anyother thin light mathe link pivoted thereto, and the spindle andeccentric for imparting movement to the link, substantially as and forthe purpose set forth.

4. In combination, the rotating platform, the link, its flexible arms h,the collar 6, the eccentric, and the block-carrier, connected with thespindle, and with means for rotating the platform, substantially as andfor'the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. I FRANCIS R. GOING. Witnesses:
